Foam Lance
A Heavy Duty Foam Lance that is constructed from a solid brass body, the extension pipe is made from zinc and fits directly onto a Karcher Pressure Washer like any other attachment. The nozzle can be adjusted for the pattern of foam delivered and the valve on the top regulates the chemical dilution rate. Using this foam lance combined with a suitable shampoo and ideally snow foam it is possible to produce a very thick layer of foam which clings to the surface of the vehicle encapsulating, softening and removing dirt making the wash process much safer and more efficient (and fun!)
Max Pressure: 200 bar, max water temp: 60°C. A wide range of adaptors are available to fit most pressure washers on the market. Simply match the adaptor to the coupling on your pressure washer.

 

TOGWT:

Thanks for your response but I am still unclear how this fits the Karcher unit. Was there supposed to be a link above? If I do a search on Amazon for "Foam Lance" the Gilmour units pop up. Can you elaborate?

Thanks,
Adam

So, of the three versions listed, which one should I get and why?

The items listed on Amazon are foam guns, the OP was asking about a foam cannon-

High Pressure Foam Cannon
The difference between this and a Gilmour Foamaster II Foam Gun is the water pressure(40 to 90 psi) usually connected to a low pressure garden hose; the HP Foam Lance (Rated Pressure - 2,300 psi) is connected to a high pressure washer (i.e. Karcher Model K5.93M or similar unit)
Also known as foam cannon, foam lance or cam spray unit; the principle behind them is to minimize the amount of paint surface friction necessary to clean the vehicle by pre-soaking it with foam. By allowing the aerated cleaning agent to dwell on the paint surface, giving the surfactants time to reduce the surface tension; so that water /foam can spread and wet the surface.
When using foam cannon, the viscosity of the product plays a huge part in how much foam is obtained and how much product is used. The foam starts loosening and lubricating the paint immediately, thus gentle touch washing with a soft mitt substantially decreases the risk of micro-marring because the paint is covered in a layer of lubrication. Its other advantage is that the surface isn't 'touched' as much as in hand washing

 

the Gilmour Foammaster II I bought is great
